Mass Transfer In a distillation operation, what is the effect of the temperature of the reflux stream (given below) on the condenser and reboiler loads? Reflux conditions:(i) Reflux stream is completely liquid and is at its bubble point.(ii) Reflux stream is below its bubble point. Condenser load is the same in both the cases but reboiler load is higher in case (ii) Reboiler load is the same in both the cases but condenser load is higher in case (ii) Condenser and reboiler loads are the same in both the cases Both condensor and reboiler loads are higher in case (ii) as compared to case (i) Condenser load is the same in both the cases but reboiler load is higher in case (ii) Reboiler load is the same in both the cases but condenser load is higher in case (ii) Condenser and reboiler loads are the same in both the cases Both condensor and reboiler loads are higher in case (ii) as compared to case (i) ANSWER DOWNLOAD EXAMIANS APP

Mass Transfer Pick out the wrong statement. Raoult's law does not apply, when the Chemical combination or molecular association between unlike molecules takes place in the formation of solution Component molecules are nonpolar Size of component molecules are not equal Attractive forces between like and unlike molecules in the solution are approximately equal Chemical combination or molecular association between unlike molecules takes place in the formation of solution Component molecules are nonpolar Size of component molecules are not equal Attractive forces between like and unlike molecules in the solution are approximately equal ANSWER DOWNLOAD EXAMIANS APP
